IMPROVEMENT EN TRUSSES FOR HERNIA.

Specification forming part of Letters Patent No,'0,57, dated November l0, 1863.

To all whom it may concern.-

Be it known that I, DANIEL C'. SMITH, of Adrian, in the county of Lenawee and State ot' Michigan, have invented a new and useful Improvement in Hernial Trusses; and I do hereby declare that the following is a full and exact description thereof, reference being had tothe accompanying drawing', and to the letters of reference marked thereon, making a part of this specitication.

The nature of my invention consists in attachinga hinge and setescrew to the spring of a truss, for the purpose of adjusting the. pressure of the spring on the rupture to any extent desired by the person wearing it, as is described in the following specification.

The accompanying drawing is a perspertive one, representing its several parts-viz., springs A, joints B B, their projections D and E, screw F, nut'G, and pivots I and J. rlhe springs A A are attached to the joint B B by means of their rivets H H. Thejoint B B is fastened together by means of the pivot I. The screw Fis attached to the projection D by means of pivot J, with its opposite end passing through the hole K in projection E. The holes L are for the purpose of attaching any kind of a pad that may be desired.

I Will describe the operation of my truss, as follows: When the person Wishes-to make the truss press harder onthe rupture, he turns the nut G on screWF in the direction to make it strike the projection E. That in turn causes joint B B to close on its pivot I, which closes the outer ends of the springs A A. Thus it is clearly seen that the person Wearing the truss can adjust the pressure of it at pleasure by turning the nut G out or in, as he pleases.

After thus having described my invention, WhatI claim, and desire to secure by Letters Patent, is

1. Tilo screw F and nut G, operatingin c0n`- nection with the projections D and E.

2. The joint B B, as above described, for the purposes set forth and described.

DANIEL G. SMITH.
